Abstract:Biomass is one of the most widely available energy sources and gasification is
a thermal conversion process where biomass is transformed into a fuel gas
with a gasifying agent. In this paper by using ASPEN Plus, a new steady state
simulation model for down draft waste biomass gasification was developed.
The model that is stoichiometric equilibrium-based is proposed to be used for
optimization of the gasifier performance. Prediction accuracy of the model is
validated by comparing with available experimental and modeling results in
other literature. Then the model is used for comparative analysis of the gasi-
fication performance of sawdust, wood chips and mixed paper wastes. In the
model, the operating parameters of temperature and equivalence ratio (ER)
have been varied over wide range and their effect on syngas composition,
syngas yield, low heating value (LHV) of syngas and cold gas efficiency
(CGE) has been investigated. Raise in temperature increases the production
of CO and H2 which leads to higher syngas yield, LHV and CGE. However,
increasing ER decreases the production of CO and H2 which results lessens in
LHV and CGE but syngas yield continuously increases because more oxygen
is available for biomass reactions at high ER. The optimal values of CO and
H2 mole fraction and CGE of sawdust, wood chips and mixed paper wastes
are located at 900˚C, 1000˚C and 1000˚C, respectively and ER range is be-
tween 0.20 - 0.35 regardless of the kind of biomass which is used as the
feedstock.
